Will DOOL be on even though the Olympics are airing right now? If they are can someone give me times so I can set my DvR?

The only day DAYS is officially pre-empted is this Monday. However, since NBC allows local affiliates to do whatever the hell they want, DAYS may get shifted to another time if your affiliate normally airs the show during the time NBC plans to broadcast the Olympics. If you normally watch the show in the later afternoon (3pm-ish or later), I'd check your local schedule just to make sure.
